The correct answer is (b), 3. The three cities/towns of Uttarakhand that have been included in the National Clean Air Programme are:
- Dehradun
- Haridwar
- Rudrapur
The National Clean Air Programme (NCAP) is a national-level action plan to combat air pollution in India. The NCAP was launched in January 2019 and aims to reduce air pollution levels in 102 cities across the country by 2024.
The NCAP includes a number of measures to reduce air pollution, including:
- Reducing emissions from vehicles
- Reducing emissions from industries
- Planting trees
- Raising awareness about air pollution
The NCAP is a comprehensive plan to address the problem of air pollution in India. It is hoped that the NCAP will be successful in reducing air pollution levels and improving the quality of life for people living in India.
The other options are incorrect because they do not reflect the number of cities/towns of Uttarakhand that have been included in the National Clean Air Programme.
